what size headers should I get?? Im looking at getting these long tube pacesetters I know I want long tube but they come in 1 5/8 inch primary tubes and 1 3/4 primary tubes and I was gonna go for the 1 3/4 but I didnt know if it would cause problems with gaskets and what not.

If you plan on future mods, go with the 1 3/4" long tubes. If the car is going to see no other mods beside the headers and maybe a CAI go with the 1 5/8".

I have read that 1 5/8" primaries might be better, or at least sufficient, for most bolt on cars. I'm not sure anyone makes a 1 5/8" long tube. I think 96capricemgr runs a 1 5/8" header on his car, and it's apparently no slouch.

Headers need to be the right size much like a cam for a given set-up. Just like many are using more cam than what they need for a given et, some are using more header primary size than necessary. Just my opinion. You might want to do a little research though. Not all that you read on these boards is 100 percent full proof, believe it or not.

There have been guys put shorties on with either 1 3/4 primaries or 1 5/8 primaries and gained very little if any. But I've never heard or long tubes with 1 3/4 primaries without a good gain. Long tubes are the ONLY way to go. You'll be dissapointed if you don't.
